我正在使用一个新的ActiveMQ 5.10.0安装，其中我在一个名为“测试”的队列中有一条消息。我还替换了bin/tivemq中的ACTIVEMQ_SUNJMX行以启用JMX：

    JMXServiceURL url1 = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://10.222.222.222:1099/jmxrmi");
    JMXConnector jmxc = JMXConnectorFactory.connect(url1);
    MBeanServerConnection conn = jmxc.getMBeanServerConnection( );
    ObjectName activeMQ = new ObjectName("org.apache.activemq:type=Broker,brokerName=TOM,connector=clientConnectors,connectorName=openwire");
//        ObjectName activeMQ = new ObjectName("org.apache.activemq:type=Broker,brokerName=TOM");


    Set<ObjectName> brokers = conn.queryNames(activeMQ, null);
    if (brokers.size( ) == 0) {
        throw new IOException("No broker could be found in the JMX.");
    }
    System.out.println("brokers.size() = " + brokers.size());
    for (int i = 0; i < brokers.size(); i++) {
        System.out.println("brokers = " + brokers.toArray()[i]);
    }
//                          ObjectName name = brokers.iterator().next();

//        BrokerViewMBean mbean = MBeanServerInvocationHandler.newProxyInstance(conn, activeMQ, BrokerViewMBean.class, true);
    ConnectionViewMBean mbean = MBeanServerInvocationHandler.newProxyInstance(conn, activeMQ, ConnectionViewMBean.class, true);
    System.out.println("        mbean.getConsumers()\n         = " +         mbean.getConsumers()
    );

抛出的异常是

 java.lang.reflect.UndeclaredThrowableException

这与线程"main"中的"Exception"java.io不同。IOException：在JMX中找不到代理。"
